I recently heard a new noise coming from my basement A/C. When the unit shuts down, it sounds as if a motor is still running, which last for approx 10 minutes, then shuts down. As a result, I have become more attune to what I don't hear and that is the second compressor kicking in.
It sounds as if it is working on reduced power yet Iam connected to 50 AMPS and the selector switch is on 50 AMPS.
Any thoughts on what may be the problem and am I doing more harm to the unit using it until I can get the problem corrected?
Thank you for any assistance.
